9.
Explain nonrenewable resources.
Correct Answer
B. Once it is gone it is gone forever - it can not be replaced in a lifetime
Explanation
Nonrenewable resources are natural resources that cannot be replenished or replaced within a human lifetime once they are depleted. These resources, such as fossil fuels and minerals, are formed over millions of years and their extraction rate exceeds their natural replenishment rate. Once they are consumed, they cannot be regenerated in a short span of time. This makes them finite and unsustainable in the long term, as their availability diminishes over time. Therefore, the statement "once it is gone it is gone forever - it can not be replaced in a lifetime" accurately describes nonrenewable resources.
